Referring to said drawings, A is the axle of ordinary form, the part shown being cylindrical. A3 is the journal. Between the journal and the body of the axle is the circumferential flange, A1. The upper part of this flange is cut away horizontally to make a horizontal face, A2, to receive a ey aswil be described further on.

the inner edges of the 4 rounding the journal and having a shoulder, B2, adapted to bear against the outer transverse face of the flange, A1. The hub has a flange, B3, extending inward over and beyond the flange, A1. The hub flange has a lateral extension, B4, on which is an inner face, B5, far-enough from. the axle to receive a key, B6, between the axle and the face, On the key is a pin or stud, B7, extending outward radially to the axle into the socket, B8, formed in the extension, B4, I

of the flange, B3. It will be observed that when this key is in position, it will bear on the face, A2, formedby cutting away the flange, A1, and thus hold the hub from turnmg on the axle, whereby the wheel ismade fast? on'the journal. When this key and pm are absent, the wheel is loose-free to turn on the journal. When the key and pin are in' position and the journal is free from the axle box and pedestal, the wheel may be moved outward on the journal, the keysliding on the face, A2, andfon the journal.

When the Wheel has been removed from the ournal, the key and pin may be removed from the hub. Then the wheel may be returned to its position to-be loose. This provision for rendering the wheel fast or loose is made because some operators of cars having the bearings distinct from the wheels prefer to have one wheel free to turn on the axle, particularly when the tracks on which the cars are used have curves. Then wh le traversing curves the wheelsmayturn independently of each other.

The part of the journal which extends outward beyond the wheel hub is surrounded by the bearing box, C. This box has an end wall, C1, extending over the end of the journal. The, inner end of said box is closed by a; cap, G2, which surrounds the journal and also the adjacent end of the hub B1. The cap has at each side of the structure a lateral ear,

.C l, which bears against a similar ear, C3, seated on the body of the bearing box.

bolt, C5, extends through the ears to bind them firmly to each other. The interior of the body of the box, C, is cylindrical. The cap, C2, has an annular shoulder, C6, extend i between said faces, in order that the rollers Wa her, terei E3 exte d through he fla ge, Cl

may rotate without being engaged by those *facesk Approximately midway between their ends, the rollers have a circumferential groove, D1; A ring, 1 ),2, surrounds the ourrial, A3, within those grooves.

Some of the lubricant passes downward through the port, C10, into the reservoir, C9, and thence through the port, G11, to t e Wa hers, E, and into th pace be een e flange, 3. .2, and he main. e l f the ap, G2. It pref rabl to introduce en ugh lu n to ause the fil ing et all 1: the grea r part of the reserVoir,"C9. This will effect immersing the lower rollers, D, in the lubricant and will cause the lubricant to rise along the washers, E, to the height of the lower part of the 'ournal and thence through the groove, B9, info the reservoir, 1310, of the hub. The Washers, El E2, are intended to substantially prevent the escaping of oil'between the cap and the hub. The rotation of the washers, E, in unison or independently of each other will cause those washers to carry oil upward and distribute the oil over all the faces of said washers. This action is aided by the wings, E4; Thus these washers will be sub'ected to a minimum of friction through contact'with each other and'with the end of the hub and with the adjacent face of the main wall of the cap. When there is end thrust tending to move the journal, A3, and the wheel, B, outward on the car body, tl1e hub, Bl, will press the large washers, E, aga nstthe m in, wal of the can U d th t con it n, luhr eet 0f he f es h Wash rs?! s needed-t0 edu e fricti between'the meeting faces of the washers and bet een the right hand washer n the main wall ofthe cap and between the left hand sher nd the nd of the From approximately midway between the cap, Q2, and the end wall, Q1, of the axle box, the uppergface of said box is horizontal in cr s. se t on nd s slanted. downward uerd th ight d toward he l f -v Thieai ed middl v rt o ee Ie beX supports the pedestal, by contact with the lQwer fact of the horizontal plate, G1, of the pedestal. The plate, G1, is secured to the car. body (not shown) in the usual manner by bolts extendin through the, bolt holes, G2. From the plate, ward at each side of the axle box in position to bear against the side of the axle box and against the ears, G3. To increase the conac betw en thes a ms and he axle bo each side of the axle ho;; is provided with an 1, arms, G3, extend downsol upright bearing face, C14. The ears serve as abutments for the pedestal arms.

Below said faces, C14, the arms are turned laterally away from each other and each is provided with an aperture, C15, which receive the ends of a stirrup rod, C16. Each end of said rod extends through the adjacent aperture and receives a nut, C17. The stirrup, rod, C16, is spaced far enough from the lower face of the axle box to allow downward movement of the axle box or upward 'movement of the pedestal when the'car is passing over irregularities in the rail track. During movement of the car, the pedestal may rock on the summit of the upper face of the axle box for maintaining the alignment of the axle box and the axle and the rollers, I), in the manner already known in this art.

It has already been stated that thrust by movement of the axle box toward the wheel hub is taken by the cap, C2, and the end of the hub and the washers, E. Thrust in the other direction is taken by the arms, G3 and the axle box ears, C3.

hen it is desired to remove the axle box, the stirrup rod, C16, is removed from the pedestal arms, G3. Then that part of the car body is raised until the pedestal arms are above the ears, C3 and C4. When that has been done, the axle box is free to be drawn outward along and oil from the journal. If the wheel is to be removed, that part of the car is to be raised sufficiently to allow the wheelto clear the pedestal arms.

The metal washers, E1, and the packing washer, E2, may be inserted and removed when the cotters, E3, have been removed.

The washers, E, are to be inserted and removed through the flanges, C12 and C13, the wings, E4, of said washers passing through the notches, C18, in the flange, C12. (Figs. 2 and 13).
